Private Mind vs Upstream

Run open AI models like Llama, Gemma, and Qwen on your phone. Offline. Private. Free. No account, no tracking, no subscription. Powered by React Native ExecuTorch. Meet Private Mind, the AI assistant that never phones home. Every conversation runs entirely on your device, so it works in airplane mode, on a plane, or anywhere the internet can't reach. Why Private Mind? · 100% offline: no internet needed, chat anywhere · Total privacy: zero telemetry, your words never leave the phone · Chat with your documents: import PDF or TXT files and get answers with clickable citations, so you can verify every source · Model Hub: curated open models grouped by family, or import your own · Built-in benchmarks: see how fast each model runs on your hardware before you commit · Local speech-to-text: dictate prompts with Whisper, transcribed on-device · Make it yours: custom system prompts, chat search, conversation forking and export Models download once (about 1 to 3 GB each, best over Wi-Fi) and stay on your device. A modern phone with 4 GB+ RAM is recommended for larger models. Not sure? Run the built-in benchmark. Free and open source.

An AI inbox that triages itself, drafts in your voice, and follows up so you don’t have to remember to. ORGANIZE EMAILS YOUR WAY Upstream sorts, flags, and surfaces what needs your attention today. Noise gets filed away. No rules to set up or folders to maintain. It learns how you work and gets out of your way. DRAFTS IN YOUR VOICE. NOT A VOICE. Upstream writes like you. Not like AI pretending to be you. It studies how you write, how you talk to this specific person, and what the thread already sounds like, then drafts from there. The reply is waiting before you've finished reading the email. THE FOLLOW-UP WRITES ITSELF Upstream watches the threads going quiet, writes the nudge, and adds it to your inbox to send. The open loops close themselves. The ball never gets dropped.
